ZERO_CROSSING_SYNCHRONIZER

Published:2009/7/13 4:14:00 Author:May | From:SeekIC

Used to synchronize firing circuit of scr's with zero crossing points of sinusoidal a-c line voltage, to initiate new timing cycle at each zero crossing and thereby permit precise control of a-c power delivered to load. In temperature control system, circuit held liquid within 0.001℃ of set point despite wide ambient temperature range.-J. D. Reed, Zero-Crossing Sync Circuit for SCR's, EEE, 12:8, p74.
